I have 2 GPU, the HD4600 and an external one. I want to use the HD4600 for OCL calculations. But I just have 1 monitor. The best way would be to disable the desktop on the second monitor. Unfortunately as soon as I do it, clGetDeviceIDs doesn't return the HD4600 anymore. The only option to enable the desktop in Win8 is to 'extend' the desktop, but then my mouse moves out of my monitor.
Is it a limitation of Windows or driver specific, that just a GPU can be used, which also shows a desktop?
